2 Claims.

The invention relates generally to dispensing containers and primarilyseeks to provide a novel container structure adapted for packaging anddispensing powdery substances, such as scouring powder or the like, anda novel holder therefor.

Cans in which scouring powder is packaged usually are formed withcardboard bodies and metallic end closures, one of said closures havingdispensing apertures therein through which the powder can be dispensed.If such cans areallowed to become wet, as by frequent contacting thereofwith wet hands, the bodies become soft and powder leaks will develop atthe junctures of the metal end closures with the bodies or in the bodywalls themselves. In order to avoid this objectionable feature it hasbeen proposed to provide can encasing holders in which to insert thedispensing cans and which protect them from wetting contact and providea dispensing unit which is neat in appearance. Such holders of which Iam presently aware have not been entirely satisfactory because of beingimpractical and unnecessarily complicated in structure. In some it hasbeen necessary to provide registering aperture sets in the holder and inthe can top, and in some clearances are provided which permitaccumulation of powder and moisture between the ends and wall portionsof the can and holder units. It is the purpose of the present inventionto provide an improved powder dispensing can and holder combinationwhich is attractive in appearance and subject to being manufactured atlow cost, and which is designed to avoid the objectionable featuresembodied in the known structures referred to hereinabove.

An object of the invention is to provide a powder dispensing can holderof the character stated having an opening in one end through which toreceive the dispensing can and which is closable with a removablymounted end closure, and an overhanging flange at its other end definingan opening through which the powder can be dispensed through thedispensing apertures in the can top, said flan e havin an annularshoulder portion engageable in sealing contact with the can top inwardlyof the periphery thereof for preventing passage of powder between saidshoulder and the can top and into the space between the can and theholder.

Another object of the invention is to provide a structure of thecharacter stated in which the can has a raised portion in its topdisposed to project upwardly through the opening. in. the holder endflange and in which the powder dispensing apertures are formed.

Another object of the invention is to provide a structure of thecharacter stated in which the raised portion on the can top has atapered annular wall with which the overhanging holder end flangeengages in sealing contact.

Another object of the invention is to provide a structure of thecharacter stated in which the can is removably held in place in theholder and with its top in sealing contact with the annular shoulder ofthe holder end flange by a threadably mounted end closure.

Another object of the invention is to provide a structure of thecharacter stated in which the holder is formed of. plastic.

With the above and other objects in view that will hereinafter appear,the nature of the invention will be more clearly understood by referenceto the following detailed description, the appended claims, and theseveral views illustrated in the accompanying drawing.

In the drawings:

Figure 1 is a top plan view of a powder dispensing can forming a part ofthe invention.

Figure 2 is a side elevation of the can shown in Figure 1 V Figure 3 isan inverted plan view of the can shown in Figure 1.

Figure 4 is a plan view of a holder structure for receiving the canillustrated in Figures 1 to 3.

Figure 5 is a side elevation and part vertical section illustrating theholder shown in Figure Figure 6 is an inverted plan view of the holderwith the bottom closure in place.

Figure 7 is an inverted plan View of the bottom closure per se.

Figure 8 is a side view of the bottom closure shown in Figures 6 and 7.

Figure 9 is a vertical cross section taken onthe line 53-9 on Figure '7.

Figure 10 is an enlarged fragmentary sectional view, parts broken away,showing the can mounted in the holder structure.

Figure 11 is an enlarged part side elevation and part vertical sectionillustrating a slightly modifled form of the invention.

In the example of embodiment of the invention herein disclosed, thereare included a powder dispensing can generally designated 5 having acardboard body 6, and a bottom end closure 1 and a top end closureclosure 8.

The top closure 8 is formed to include a raised, centrally disposedcircular portion or knob extension 3 which is preferably surrounded by atapered or frusto-conical wall portion H] which is in turn surrounded bythe main body portion ll of the closure which also may befrusto-coniform in shape. Like the bottom closure 7, the top end closure8 may be secured to the body 6 in any approved manner, as by a rolledseam [2. In the simple illustration herein disclosed, the tapered,circular knob or protuberance defining wall l l is disposed at an angleof 45, but it is to be understood that this particular angle ofprojection of said wall may be modified without departing from thepurpose of the invention.

It will be apparent by reference to Figure l of the drawings that theraised knob or protuberance on the top closure of the can is providedwith the usual punch-out apertures l3 through which powder may bedispensed from the can.

The holder structure in which the can illustrated in Figures 1, 2 and 3is removably mountable is illustrated in Figures 4, 5 and 6. This holderpreferably is constructed of a molded plastic and includes a generallycylindriform body l -l which may be slightly tapered toward the top inthe manner clearly illustrated in Figure 5. The body It is open at oneend as illustrated in Figures 5 and 6 so as to facilitate introductionof the powder dispensing can thereinto, and the open end of the body ischamfered as at 5 and provided with an internal thread it. At its otheror upper end the holder is provided with an inwardly turned flange lldisposed to overhang the top end of the powder dispensing can when it ismounted in the holder in the manner clearly illustrated in Figure 10.The flange ll defines a central opening I8 disposed to receive theraised portion or knob 9 extending from the powder dispensing can, andsaid opening preferably is flared, as at W, at the same angle as thetapered can projection wall portion 49 in order to provide a sealingseat presented for sealing contact with said tapered wall portion. Itwill be obvious that the inwardly directed flange il has a certainamount of resiliency inherent there- The closure for the bottom of thepowder dispensing can and casing holder is illustrated in detail inFigures '7, 8 and 9 and preferably is formed of molded plastic. Thisclosure comprises a disk generally designated 28 having a convex centerbody 2i shaped to provide a can end abuttin annulus 22 which issurrounded by an outwardly directed flange 23. The flange 23 is shapedto form a single helical thread 2 3, and to include finger pieces 25which will facilitate threading of the closure into the internal threadH5 or the holder i i in effecting a closure of the holder as illustratedin Figure 6. It will be apparent by reference to Figure 9 that theclosure member is in the nature of a thin shell having inherentresiliency, and when the closure is threaded into the lower end of theholder is it will engage the bottom end of the powder dispensing can inthe manner illustrated in Figure 10 and will secure the can in theholder and maintain a resilient contact between the flange H and the topof the can inwardly of the periphery of the can top, or morespecifically will maintain a resilient contact between the internallyflared sealing wall 59 of the flange and the externally tapered sealingor seating wall ll! surrounding the central protuberance or knob 9 ofthe can top. It will be apparent by reference to Figure 10 that theparts are so proportioned that the peripheral portion Of the can top, orin other words the seam E2, is held out of contact with the holderflange H and thus cannot interfere with the sealing contact between theholder flange and the can top protuberance or knob.

With the can mounted in the holder in the manner clearly illustrated inFigure 10, the powdery substance may be dispensed from the can throughthe punched apertures l3 without any interference by the holder flangeIT, and the sealing contact of the flange with the can top protuberanceor knob assures against leakage of the powder between the can top andthe flange, and also into the space surrounding the can within theholder.

In Figure 11 of the drawings, there is illustrated a slightly modifiedform of the invention in which the powder dispensing can is providedwith a cylindriform raised portion or protuberance 21. In this form ofthe invention the raised portion 21 of the can top has a rather snug fitin the opening 28 in the holder flange 29, said flange having aninherent resiliency as in the previously described form of theinvention, and being equipped with a flared sealing wall portion 36. Thesealing wall portion 38 of the holder flange is disposed to engage insealing contact with the frusto-coniform main body portion 3| of the cantop which surrounds the apertured central protuberance or knob 27. As inthe previously described form of the invention the contact of thesealing surfaces 30 and 3| of the flange and can top respectively servesto prevent infiltration of powder into the holder in the space betweenthe can and the internal wall portions within said holder, and the seam32 by which the can top is secured to the can body 33 is held away fromthe adjacent end extremity or flange of the holder as at 34 so that itcannot interfere with the efficient sealing contact between saidsurfaces 36 and 3 I.

While preferred forms of the invention have i been shown for purposes ofillustration, it is to be clearly understood that various changes in thedetails of construction and arrangement of parts may be made withoutdeparting from the spirit and scope of the invention as defined in theappended claims.
